    Many causes can lead to LogListener heartbeat exception. Possible causes include:

    • Network error

      telnet <cls domain name> 80

      Check the network connectivity. For more information about the CLS domain name, see Available Regions.

    • Incorrect key

      To check the LogListener key, access the LogListener installation directory and run the following command.

      grep secret etc/loglistener.conf

    2. Check for IP address of the server group

    Check that the IP address added to the server group is the one configured on LogListener during installation. Run the following command to check the IP address configured on LogListener.

    grep group_ip etc/loglistener.conf

    Log in to the CLS Console, and select Server Group on the left sidebar. On the Server Group Management page, view and verify that the IP address of the server group is the same as that configured on LogListener.
